Explanation:

Correct option 2: Sunday

Given that:-
(365-31-28-31-30) = 245
• No of days from 1 May 1983 to 13 August 1989- • Days in year 1983 after 30 April 1983 • Days in year 1984, 1988 366 • Days in year 1985, 1986, 1987 • Days in year 1989 upto 13 August
366 (leap year) = 732 365+ 365+ 365
1095
(31+28+31 +30 +31 +30 +31 + 13) = 225
• Total no. of days = 245+ 732 + 1095 225 = 2297
• Since, it was Saturday on 30 April 1983, every 7th day from 30 April will be a Saturday.
• Thus, no. of odd days = 2297/7=1
• Now, 30 April 1983 (Saturday) + 1 odd day = 13 August 1989 (Sunday)
• 13 August 1989 will be Sunday.
